Nothing but hassle costomer service is appalling 3 phone calls 1 and half hours on hold or waiting, something as simple as an issue with topping up with a fault on there system now means that we have to wait up to five days for a refund before we can get our money back but no apology or option for them to credit the account unless we are in financial distress, don't use this energy supplier unless you have deep pockets and enjoy long evenings on hold we will be changing ASAP only been with them 8 months loads issues only one of those times we felt like they were interested in trying to help
